target temperature changes automatically

[Schlicki]

I have some TRV combined with an external sensor in BT. When I set a target temperature - 19° for example - manually

some moments later BT changes the target temp without any sense

Can’t see anything in the log, as no action is listed. How can I solve this? Calibration via offset is not available in the config and mode ‘AI time based’ shows the same behaviour.

The debug log after setting target to 20° for example:

This is intended. BT improves the internal algorithm of your Thermostat by setting its target heatping point to a extreme value.

You can (and should) install the BT Card (https://github.com/KartoffelToby/better-thermostat-ui-card) this UI component displays the actual heating target.

[Schlicki]

Can't imagine it is inteded to heat the room although it is already hotter than the initial target temperature set by me.

I switched to the actual beta of BT and that issue seems to be solved as there is no random target temperature change anymore until now.

[ovizii]

I am having the exact same issue, and I am using the BT card. I left my home this morning at 7am and I am wondering why BT decided that it needs to ramp up the desired target temperature from 19.5 to 22.5? I then switched it back to 19.5 only to find it had fallen to 9.5 later on. :-/

I am on a non-beta version, will try to use a beta now too and see if it's fixed.

[Schlicki]

Get the latest beta and try it. Seems to work without that target temp error.

[ovizii]

I've run the latest BT beta for the last 2 days and today when I updated HA Core, after the restart BT felt I need more heat in my bedroom (in my absence)

Update: there seems to be no relation between the update and BT. BT raised the target temperature before the update was done.

I have the same issue. When heating up from Eco (18°) in the morning to 21,5° the target temperature jumps unintended to 28°. I'm using the BT card. I have to set back the target temperature manually to 21,5° several times until it stays there.

[dieterpapa]

Same is the other way - set BT card to Eco temperature - BT sets all Climate entities to minimum temperature. After some time also the Target temperature in BT card sets to 8°.
